The ivory gull Pagophila eburnea is a high‐Arctic species threatened by climate change and contaminants. The objective of this study was to assess spatial variation of contaminant levels (organochlorines ‘OCs’, brominated flame retardants ‘BFRs’, perfluorinated alkyl substances ‘PFASs’, and mercury ‘Hg’) in ivory gulls breeding in different areas across the Arctic region as a baseline for potential future changes associated with climate change. Contaminants were already determined in eggs from Canada (Seymour Island – except PFASs), Svalbard in Norway (Svenskøya), and 3 sites in Russia (Nagurskoe, Cape Klyuv, and Domashny). New data from Greenland allowed the investigation of a possible longitudinal gradient of contamination. The most quantitatively abundant OCs were p,p′‐DDE (dichlorodiphenyldichloroethylene) and ΣPCB (polychlorobiphenyl). Mercury concentrations were higher in Canada compared to other colonies. Eggs from Nagurskoe were often characterized by higher OC and BFR concentrations. Concentrations gradually decreased in colonies situated east of Nagurskoe. In contrast, PFASs concentrations, especially PFOA (perfluorooctanoate) and PFNA (perfluorononanoate), were higher in Greenland. Some of the contaminants, especially Hg and p,p'‐DDE, exceeded published threshold levels known to disrupt the reproductive success of avian species. Overall, the levels of OCs, BFRs and PFASs did not suggest direct lethal exposure to these compounds but their potential synergetic/additive sublethal effects warrant monitoring.

Background
Wuhan is the capital city of Hubei province in central China and has 166 lakes that cover 2,217 square km (856 square miles) and approximately 25% of the city. This surface water coverage is one of the world’s highest. The Wuhan Environmental Protection Bureau (WHEPB website: http://www.whepb.gov.cn) is responsible for monitoring the surface water quality within the city borders and does this by monitoring a subset of 50 lakes on a yearly basis for temperature, conductivity, pH, dissolved...

Why Monitor Gas and Thermal Energy?
Hang on, are you telling me you are an energy manager that’s only worried about electricity!? Let’s take a step back and realise that gas represents nearly 40% of the total energy consumed in the industrial and service sectors in Europe. That’s almost half, you guys!
And it’s no wonder – we need gas for heating, but also cooking and countless industrial processes. Plus, gas is 60% cheaper than electricity in the majority of European countries...

Abstract
Inorganic nitrate and nitrite from dietary and endogenous sources are metabolized to NO and other bioactive nitrogen oxides that affect blood pressure. The mechanisms for nitrite bioactivation are unclear, but recent studies in rodents suggest that gastric acidity may influence the systemic effects of this anion. In a randomized, double-blind, placebo-controlled crossover study, we tested the effects of a proton pump inhibitor on the acute cardiovascular effects of nitrite. Fifteen healthy nonsmoking,...
